Re: import antenna pattern
Thanks for your reply.
Apart from Feko,
do you know if the imported pattern can be used as impressed source and if they can be traslated in to huygens source or SWE?
Thanks a lot
import antenna pattern
I would liek to konw if you are aware of any simulation tool able to import a pattern of antenna from an ascii file and use it as source in the simulation of a scattering objetc.
Thanks a lot
Re: Interior Wave Ports
Place a thin box with of perfect conductor
with the face coincident with the rectangle to which you want
assign the waveport
then assign the waveport to the rectangle
Hope this helps

I used all these software and my opinion is that
FEMLAB is a very good tool when you have to solve a
highly specialized problem such as a coupled problem
CST and Ansoft seems to me a better solution for a general purpose tool
it is not necessary to make the coax cable so long to get
the border of the external box.
you can use a so called cap.
1)attach the port to the bottom surface of the coax
2) draw a thin cylinder made by perfect conductor exactly on the bottom surface of the coaxial with the same external radius...
HFSs will apply a perfect E bounday condition to all external surfaces of a model
To be sure about the real BC applied to a certain model you must verify the BC before to start the simulation.
I would bet that
the BC in your model are different to what you believe.
In any case the surface...
you have several possible choise.
1) you could reproduce the feed as it is in phisical reality
this means you need to draw the real feed
supposing it is a coaxial feed
you must draw the coax cable attach the internal pin to one of the triangle...and so on...
the port in this case it is a...
Re: How to calculate difference mode trace with 100ohm imped
you may use 2d field simulator to calculate the impedance of traces
go at www.ansoft.com and download Maxwell software you can draw your cross-section and calculate on your own the LC parametr and the impedance of your configuration
